Google Professional Cloud Developer Exam - Topic 6 Question 103 Discussion

Actual exam question for Google's Professional Cloud Developer exam

Question #: 103
Topic #: 6

[All Professional Cloud Developer Questions]

You work on an application that relies on Cloud Spanner as its main datastore. New application features have occasionally caused performance regressions. You want to prevent performance issues by running an automated performance test with Cloud Build for each commit made. If multiple commits are made at the same time, the tests might run concurrently. What should you do?

ACreate a new project with a random name for every build. Load the required data. Delete the project after the test is run.

BCreate a new Cloud Spanner instance for every build. Load the required data. Delete the Cloud Spanner instance after the test is run.

CCreate a project with a Cloud Spanner instance and the required data. Adjust the Cloud Build build file to automatically restore the data to its previous state after the test is run.

DStart the Cloud Spanner emulator locally. Load the required data. Shut down the emulator after the test is run.

C is definitely the most practical approach here.

Surprised that D is even an option, does the emulator really work well?

A sounds like a hassle, too many projects to manage!

I disagree, C would be more efficient in the long run.

Option B seems like the best choice for isolation.

Starting the emulator seems like a safe bet, but I’m not entirely confident if it would mimic the production environment accurately enough.

I practiced a similar question where we had to manage resources efficiently. I feel like option B could be overkill, creating too many instances.

I think option C sounds familiar; it might help maintain a consistent state, but I wonder if it could lead to data conflicts with concurrent builds.

I remember we discussed the pros and cons of creating new instances for tests, but I'm not sure if that's the best approach here.

I'm leaning towards option B. Creating a new Cloud Spanner instance for each build could help isolate the tests and prevent any interference.

I think option C might be the way to go. Restoring the data state after the test seems like the most reliable approach.

Ah, I see. Using the Cloud Spanner emulator could be a good solution, but I'll need to make sure the data is properly loaded and unloaded.

Hmm, creating a new project for every build sounds like a lot of overhead. I wonder if there's a more efficient way to handle this.

This seems like a tricky one. I'll need to think through the options carefully to make sure I don't miss anything.

I bet the developers who come up with these exam questions have a blast trying to trip us up. 'Delete the project after the test?' Sounds like a recipe for disaster!

Why not just use a single project and instance, and reset the data state after each test? Option C sounds like the most efficient and cost-effective approach.

That makes sense, it's important to optimize the testing process to prevent performance regressions.

Creating a new project for every build is a bit overkill, in my opinion. Option A might work, but it could get expensive with all the project creation and deletion.

I like the idea of using the Cloud Spanner emulator locally, as it avoids the overhead of provisioning and deleting instances. Option D could be a good choice if the emulator accurately represents the production environment.
